We determined velocity discrimination thresholds and Weber fractions for sounds revolving around the listener at very high velocities. Sounds used were a broadband white noise and two harmonic sounds with fundamental frequencies of 330 Hz and 1760 Hz. Experiment 1 used velocities ranging between 288°/s and 720°/s in an acoustically treated room and(More)
Three experiments are reported, which investigated the auditory velocity thresholds beyond which listeners are no longer able to perceptually resolve a smooth circular trajectory. These thresholds were measured for band-limited noises, white noise, and harmonic sounds (HS), and in different acoustical environments. Experiments 1 and 2 were conducted in an(More)
With the emergence of electroacoustic music, spatial figures have become part of the musical vocabulary of many composers. But the perception of auditory trajectories has received scant attention in the scientific literature. This study aims at determining under which conditions simple common spatial figures (such as circles, squares and triangle) can be(More)
1 donin (at) ircam(dot)fr, 2 feron (at) ircam(dot)fr ABSTRACT In 2009, internationally renowned composer Stefano Gervasoni authorized researchers to delineate the genesis of his then most recent piece, Gramigna, a cycle of miniatures that was soon to be developed into an expanded version. The creative process of the existing version of Gramigna was(More)
We report two experiments investigating rotating sounds presented on a circular array of 12 speakers. Velocity thresholds were measured for three different types of stimuli (broadband noises, white noise, harmonic sounds). In the first experiment, we gradually increased or decreased the velocity and asked participants to indicate the point at which they(More)
